I'd like a cordless trimmer and wonder about an electric one as opposed to
a petrol one.
Seems then that cordless electric would not do the job properly in one session.

I have a Stihl petrol trimmer, which has been excellent, for quite a
few years, however due its weight and the fact that parts of my beech
hedge are high and fairly inaccessible I bought a GTech telescopic
cordless trimmer which was on offer through the Telegraph last year.(
See http://www.greytechnology.co.uk/HT01.php) I have found it very
good, especially for trimming soft new growth. I also bought a second
battery but so far all trimming has been done on one battery which is
worn on a waist belt.

I can recommend the cordless trimmer however it could not cope with
thicker, woodier growth which is where the Stihl comes into its own.

I like my GTech. Great for the extra reach from ground level or from a
ladder and for angled cuts, eg slicing off the top growth of a bulky
shrub.
